Can anyone advise what does "coordinate number-letter-number" means on fire dispatch Talkgroup? I hear them on Baltimore City and Anne Arundel fire dispatch but never understand what they mean, for example

Baltimore City does occasionally announce the MPDS determinant for EMS responses, but I'm not sure why because almost NO ONE knows what they mean. A quick google search or a search of this forum will produce a list of MPDS dispatch codes.
